Ali Saidi 8561c8366c fix smul and sdiv to sign extend, and handle overflow/underflow corretly 
Only allow writing/reading of 32 bits of Y
Only allow writing/reading 32 bits of pc when pstate.am
Put any loaded data on the first half of a micro-op in uReg0 so it can't
overwrite the register we are using for address calculation
only erase a entry from the lookup table if it's valid
Put in a temporary check to make sure that lookup table and tlb array stay in sync
if we are interrupted in the middle of a mico-op, reset the micropc/nexpc
so we start  on the first part of it when we come back

    overwrite the register we are using for address calculation
src/arch/sparc/isa/includes.isa:
    Use limits for 32bit underflow/overflow detection
src/arch/sparc/tlb.cc:
    only erase a entry from the lookup table if it's valid
    Put in a temporary check to make sure that lookup table and tlb array stay in sync

    add a print function to dump the tlb lookup table

checker Rename the StaticInst-based (read|set)(Int|Float)Reg methods to (read|set)(Int|Float)RegOperand to distinguish from non-StaticInst version. 2006-12-12 09:58:40 -08:00
memtest little fixes i noticed while searching for reason for address range issues (but these weren't the cause of the problem). 2006-12-15 17:55:47 -05:00

base.cc the way i understand it, interrupts in m5 is a little bloated. the usage of CPU->checkInterrupts bool is inconsistent, and i think should eventually be phased out. For now, I've just assumed that CPU->checkInterrupts() is the way to fast path a CPU if you have no interrupts by having a simple bitfield in each ISA to determine whether interrupts are pending. getInterrupts has been mostly filled in. 2007-01-08 18:18:28 -05:00

cpuevent.cc Change ExecContext to ThreadContext. This is being renamed to differentiate between the interface used objects outside of the CPU, and the interface used by the ISA. ThreadContext is used by objects outside of the CPU and is specifically defined in thread_context.hh. ExecContext is more implicit, and is defined by files such as base_dyn_inst.hh or cpu/simple/base.hh. 2006-06-06 17:32:21 -04:00

thread_context.hh Change the connecting of the physPort and virtPort to the memory object below the CPU to happen every time activateContext is called. The overhead is probably a little higher than necessary, but allows these connections to properly be made when there are CPUs that are inactive until they are switched in. 2006-11-29 16:07:55 -05:00
thread_state.cc Change the connecting of the physPort and virtPort to the memory object below the CPU to happen every time activateContext is called.
